I think stainless steel bowls should be o.k. for both water and food. I had a set of stainless steel bowls I used for years, with no problems. I use ceramic bowls now.
I think the danger from the metal bowls comes from the aluminim bowls and pans. I'm not sure of the scientific aspect of it, but I think it has something to do with interaction between the metal and bacteria. It has always been my understanding that stainless steel is safe, and does not pose this hazard.
